Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487020, here are decompositions:

  • 23 + 33486997 = 33487020
  • 67 + 33486953 = 33487020
  • 79 + 33486941 = 33487020
  • 103 + 33486917 = 33487020
  • 157 + 33486863 = 33487020
  • 163 + 33486857 = 33487020
  • 173 + 33486847 = 33487020
  • 179 + 33486841 = 33487020

Showing the first eight; more decompositions exist.
